Buildbot writes observed logs (most commonly stdout and stderr) to the status UI. However, we've noticed that often times we know the build is past a certain step but the logs we can see through the autobuilder status UI haven't been updated to reflect the latest output from bitbake. We'd like to have the log output synced more frequently, particularly for things like oe-selftest. It may be that syncing on a timer (i.e. every minute) would be more useful for our needs than syncing on a chunk size (i.e. every 4kb) — assuming that's what currently happens.
New buildbot does much better at this.
